Arrived around 11:30 from my flight with my next one departing at 7:30 am so I decided to just stay the night and avoid the hassle of leaving and coming back. After snagging my bags from bag check, I came back upstairs and found a spot at a table at Love Landing (the only spot they allow overnight travelers). There were about 10-15 other people. I’d recommend bringing some headphones or ear plugs. Security opens up at 4 am.
